i just read on the ruby-talk list (about the Ruby programming language) that they have a wiki 'tarpit' that spammers get routed to. it looks like the real wiki, and it's all they can see, so when they change it it's changed. they think they've spammed the wiki, and leave. it seems the ruby wiki has had other spam protection methods in the past, and since spammers could see they were being circumvented, they tried a lot of things to go around the protection. so if you visit their wiki, and your IP address doesn't reverse-lookup (i.e. there's no name for your ip address), and you haven't set any user preferences, you are judged to be a spammer and routed to the 'tarpit', the fake wiki. (of course they have a list of known non-spammers, and a list of spammers for which the above predicates aren't true.) the wiki maintainer then has to look occasionally for innocent users who've been accidentally routed to the tarpit, and 'rescue' them. but he said that in 46 updates to the tarpit (and 93 to the real wiki), only three updates had been innocent users updating the tarpit. i thought you all might be interested, what with the recent koha wiki spam problems. what's our spam like, anyway? am i right to assume it's mostly automatic spam, since the clearly readable username/password authentication is keeping it out?
